The best way to do it is to activate Sky Talk Shield - our free call screening service that lets you answer the calls you want to and block the ones you don't.
But if you haven't got Sky Talk Shield or we've told you that you can't get it, you can still block calls with Last Call Barring.
To block a specific number:
- Dial 1 4 2 5 8 and choose - bar a specific number.
- Dial the number you want to block then press #.
To block the last number that called:
- Dial 1 4 2 5 8.
- Press '*' twice and confirm that you want to block calls from that number.
To unblock or to hear a list of blocked numbers, dial 1 4 2 5 8 and follow the instructions. You might be asked for a PIN, if you haven't changed this try the default 1234.
Last call barring is an optional extra.
